Technical Field
[0001] This utility model relates to a device for curling and collecting edge material from polarizing plates, belonging to the technical field of polarizing plate production equipment. Background Technology
[0002] The traditional edge material curling mode of polarizing plate cutting machine is: machine cutting → manual edge material collection. The efficiency of manual edge material collection has a bottleneck and cannot match the changes in the cutting speed of the cutting machine in real time. At the same time, the edge material collected manually is relatively messy, which affects the cleanliness of the production site, and subsequent processing is also time-consuming and labor-intensive. Therefore, an effective solution is needed to improve production efficiency, reduce production labor costs, and maintain the cleanliness of the production site. Utility Model Content
[0003] In order to solve the problems existing in the prior art, this utility model provides a device for curling and collecting the edge material of a polarizing plate.
[0004] The technical solution of this utility model is as follows:
[0005] A device for curling and collecting edge material from polarizing plates includes a fixed guide roller, a movable guide roller, and a take-up roller spanning above a production line. The fixed guide roller is located between the movable guide roller and the take-up roller, and the positions of the fixed guide roller, the movable guide roller, and the take-up roller increase sequentially in height. The take-up roller is driven to rotate by a drive device. The edge material from the polarizing plates on the production line is guided by the fixed guide roller and the movable guide roller in sequence and then wound onto the take-up roller. A bracket is installed on the production line, and a suspension shaft parallel to the movable guide roller is set at the top of the bracket. Two suspension arms are rotatably connected to the suspension shaft, and the two suspension arms hang naturally. The two ends of the movable guide roller are respectively connected to the hanging ends of the two suspension arms.
[0006] As a preferred embodiment of this utility model, the fixed guide roller and the movable guide roller have the same structure, both including a shaft and a cylinder. The shaft passes through the inside of the cylinder, and the shaft and the cylinder are rotatably connected by at least two bearings, so that the cylinder can rotate relative to the shaft. The shaft is used for fixing, and the outer circumferential surface of the cylinder forms sliding friction and rolling friction contact with the edge material of the polarizing plate.
[0007] As a preferred embodiment of this utility model, support members are installed on both sides of the production line, and the two ends of the fixed guide roller are respectively connected to the two support members.

Support plates are respectively provided on the top of the two longitudinal rods, and the two ends of the suspension shaft are respectively connected to the two support plates.
[0009] As a preferred embodiment of this invention, the suspension arm is rotatably connected to the suspension shaft via a damping bearing. Under the action of the damping bearing, the rotation between the suspension arm and the suspension shaft has a damping effect, preventing the suspension arm from being too flexible and swinging freely during natural descent.
[0010] As a preferred embodiment of this invention, the suspension arm is provided with a weight-reducing hole to reduce its own weight.
[0011] As a preferred embodiment of this utility model, a column is vertically installed on one side of the production line, one end of the receiving roller is rotatably connected to the column, and the driving device is installed on the column.

[0013] To facilitate the removal of the edge material of the wound polarizing plate, the take-up roller adopts a tile-type air-expanding shaft.
[0014] As a preferred embodiment of this utility model, a receiving tray is provided below the receiving roller, and a frame is provided at the bottom of the receiving tray, the frame being connected to the production line; the receiving tray can prevent the polarizer edge material debris from falling onto the production line during the rotation of the receiving roller or during the unloading of the wound polarizer edge material.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0029] like Figure 1-5 As shown, this embodiment is a device for curling and collecting edge material from polarizing plates, including a fixed guide roller 1, a movable guide roller 2, and a take-up roller 3 spanning above the production line 4. The movable guide roller 2 is located on the side of the production line 4 in the material receiving direction, and the take-up roller 3 is located on the side of the production line 4 in the material receiving direction. The fixed guide roller 1 is located between the movable guide roller 2 and the take-up roller 3, and the positions of the fixed guide roller 1, the movable guide roller 2, and the take-up roller 3 increase sequentially in height. The take-up roller 3 is driven to rotate by a drive device. The edge material 5 of the polarizing plates on the production line 4 is guided by the fixed guide roller 1 and the movable guide roller 2 in sequence and then wound onto the take-up roller 3. A bracket is installed on the production line 4, and a suspension shaft 6 parallel to the movable guide roller 2 is set at the top of the bracket. Two suspension arms 7 are rotatably connected to the suspension shaft 6. The two suspension arms 7 hang down naturally, and the two ends of the movable guide roller 2 are respectively connected to the hanging ends of the two suspension arms 7.
[0030] like Figure 3As shown, in this embodiment, the fixed guide roller 1 and the movable guide roller 2 have the same structure, both including a shaft 11 and a cylinder 12. The shaft 11 passes through the inside of the cylinder 12, and the shaft 11 and the cylinder 12 are rotatably connected by two bearings 13. The two bearings 13 are respectively close to the two ends of the shaft 11. In actual application, the number of bearings 13 can be appropriately increased as needed to allow the cylinder 12 to rotate relative to the shaft 11. The shaft 11 is used for fixing, and the outer circumferential surface of the cylinder 12 forms sliding friction and rolling friction contact with the polarizing plate edge material 5. The two ends of the shaft of the movable guide roller 2 are respectively connected to the drooping ends of the two suspension arms 7.
[0031] In this embodiment, support members 14 are installed on both sides of the production line 4 respectively, and the two ends of the fixed guide roller 1 are connected to the two support members 14 respectively, that is, the two ends of the shaft 11 of the fixed guide roller 1 are connected to the two support members 14 respectively.
[0032] like Figure 1 and 5 As shown, the support includes two longitudinal rods 8 and two transverse rods 9, the number of which can be appropriately increased or decreased in actual application; the two longitudinal rods 8 are vertically installed on both sides of the production line 4, and the two transverse rods 9 are connected between the two longitudinal rods 8. Support plates 10 are respectively installed at the top of the two longitudinal rods 8, and the two ends of the suspension shaft 6 are respectively connected to the two support plates 10; Figure 2 As shown, the suspension arm 7 is rotatably connected to the suspension shaft 6 via a damping bearing 15. Under the action of the damping bearing 15, the rotation between the suspension arm 7 and the suspension shaft 6 has a damping effect, preventing the suspension arm 7 from being too flexible and swinging freely during natural descent. In this embodiment, a weight-reducing hole 16 is formed on the suspension arm 7 to reduce the weight of the suspension arm 7 itself.
[0033] In this embodiment, a column 17 is vertically installed on one side of the production line 4, and one end of the receiving roller 3 is rotatably connected to the column 17. The driving device is installed on the column 17. The driving device includes a motor 18 and a reversing reducer. The motor 18, the reversing reducer and the receiving roller 3 are sequentially connected for transmission.
[0034] To facilitate the removal of the wound polarizing plate edge material 5, the take-up roller 3 in this embodiment adopts a tile-type air expansion shaft. When winding and collecting the polarizing plate edge material 5, the tiles of the tile-type air expansion shaft are in an expanded state. When removing the wound polarizing plate edge material 5, the tiles of the tile-type air expansion shaft are in a contracted state, thereby facilitating the removal of the wound polarizing plate edge material 5.
[0035] In this embodiment, a receiving tray 19 is provided below the receiving roller 3, and a frame 20 is provided at the bottom of the receiving tray 19. The frame 20 is connected to the production line 4. The receiving tray 19 can prevent the dust of the polarizing plate edge material 5 from falling onto the production line 4 during the rotation of the receiving roller 3 or during the disassembly of the wound polarizing plate edge material 5.
[0036] During operation, the conveying speed of production line 4 changes with the cutting speed of the cutting machine. If the take-up roller 3 rotates slowly and the conveying speed of production line 4 is fast, the polarizing plate edge material 5 will become loose, leading to contact contamination of the polarizing plate product. If the take-up roller 3 rotates fast and the conveying speed of production line 4 is slow, the polarizing plate edge material 5 will be pulled too tight, potentially causing it to break. Therefore, this embodiment includes a movable guide roller 2 on the take-up path of the polarizing plate edge material 5. The movable guide roller 2 can naturally droop under gravity and swing within a certain angle range. When the take-up roller 3 rotates slowly and the conveying speed of production line 4 is fast, causing the polarizing plate edge material 5 to become loose, the movable guide roller 2 swings downward at a certain angle under gravity. Figure 4 As shown, this prevents the polarizer edge material 5 from becoming loose; when the take-up roller 3 rotates at a relatively fast speed and the production line 4 conveys at a relatively slow speed, and the polarizer edge material 5 is about to be pulled too tight, the polarizer edge material 5 pulls the movable guide roller 2 to swing upward at a certain angle, such as... Figure 1 As shown, the stretching path of the polarizing plate edge material 5 has a certain range of motion, thereby preventing the polarizing plate edge material 5 from being stretched too tightly and effectively preventing the polarizing plate edge material 5 from contacting and contaminating the polarizing plate product due to slackness or from being stretched too tightly and breaking.
